block

Get blocks by reference

If a hash is passed, returns the matching block. If a number is passed, gives the blocks by that number - could be multiple blocks if there's a pruned block in that slot.

Path parameters

block_refstring required

Block reference. Either a block number (integer ≥ 0), or a block hash in hex (with or without 0x prefix, case-insensitive).

Response

List of matching blocks.

eventCountinteger required

Number of events in the block.

extrinsicCountinteger required

Number of extrinsics in the block.

extrinsicRootstring required

32-byte Blake2b-256, always 0x-prefixed and lowercase in responses. Inputs elsewhere may accept mixed case or missing 0x; the API normalizes outputs.

hashstring required

32-byte Blake2b-256, always 0x-prefixed and lowercase in responses. Inputs elsewhere may accept mixed case or missing 0x; the API normalizes outputs.

numberinteger required

Block height.

parentHashstring required

32-byte Blake2b-256, always 0x-prefixed and lowercase in responses. Inputs elsewhere may accept mixed case or missing 0x; the API normalizes outputs.

specVersioninteger required

Runtime spec version.

stateRootstring required

32-byte Blake2b-256, always 0x-prefixed and lowercase in responses. Inputs elsewhere may accept mixed case or missing 0x; the API normalizes outputs.

status'proposed' | 'pruned' | 'finalized' required

Block status.

finalized: Blocks that have been finalized on chain.
proposed: Blocks that have been authored but not yet finalized.
pruned: Blocks that have been removed or are no longer accessible.

timestampinteger

Block timestamp. Milliseconds.

weightobject

Block weight in JSON format. Schema depends on runtime metadata.
